The position of your fingers on the stick is not as important. Choose what is comfortable for you. Some people find that having you pinky hanging off the edge helps to increase movement and rotation on the dominant hand’s wrist.
Your knees should be bent in an athletic stance and your body should be positioned at a 45 degree angle in relation to the net or wherever you are shooting.
For the wrist shot, the puck should be positioned at your back foot. This will allow you to have more leverage and thus more power.Do not put the puck so far back that it is uncomfortable. Try to get the puck as close to your back foot while still being in a comfortable position
Sweep the puck forward while transferring your weight toward your front foot and rotating your body forward. Your hips and shoulders should turn toward your target.The rotation should be a quick turn but not so quick that it hurts your back or makes your shot unstable.
